Honeywell 51202971-112
Overview
The 51202971-112 is a high-performance Combo I/O-Link cable for Honeywell Series 8 / C300 DCS systems. It delivers both power and I/O-Link communication through a single connection, supporting a 6-drop daisy-chain configuration that connects up to six I/O modules to the High Performance Monitoring Module (HPMM) or C300 controller. The cable is built with shielded, EPR-insulated conductors and M12 X-type industrial connectors for reliable data transmission in demanding industrial environments.

Applications
Factories, warehouses, and industrial automation networks running Honeywell Series 8 C300 controllers; process industries requiring flexible, redundant I/O connectivity.
Installation & Notes
Route through designated cable trays, avoiding sharp bends and proximity to high-voltage power lines. Engage M12 X-type connectors firmly into I/O modules and HPMM. The cable supports hot-swapping — modules can be replaced without system shutdown. Verify redundant power feed wiring per Honeywell Series 8 I/O-Link planning guidelines. Select the appropriate length variant (2/5/10/20 m) to match cabinet layout; the 22 AWG conductor gauge and 7.5 mm OD must be accounted for in tray fill calculations.
